Theoretical and Experimental Study of Honey’s Viscosity in three Southern States of Nigeria: Application of Vogel-Tamman-Fulcher (VTF) And Power Law (PL) Models

Abstract

In this study, we employed Power-law (PL) and Vogel, Tamman and Fulcher (VTF) models, to evaluate viscosity as honey’s property of rheological origin. Five samples of local market honey and three samples of farm honey collected from some states in Southern Nigeria were evaluated.

Using the linearization of these models, all necessary constants in the resulting equations were obtained. The assessment of these models for their suitability in this study were carried out on the basis of regression analysis, with the aid of resulting correlation coefficients (R).

The results obtained showed that the values of correlation coefficient of these models were suitable for the study of viscosity using the samples of honey as a major rheological property owing to their good correlation coefficients. The obtained results qualitatively agree with those discussed in the literature.
